Abstract
A biosignal measurement device includes: a first chopper amplifier circuit that receives a biosignal detected by a measurement electrode contacting a living body, and is chopper-controlled based on a first control signal; and a controller that selectively performs one of a biosignal measurement mode operation for outputting the first control signal having a first frequency to the first chopper amplifier circuit and a test mode operation for outputting the first control signal having a different frequency from the first frequency to the first chopper amplifier circuit.
Claims11
A biosignal measurement device, comprising:
- a first chopper amplifier circuit that receives a biosignal detected by a first electrode contacting a living body, and is chopper-controlled based on a first control signal;
- and
- a controller that selectively performs one of:
- a biosignal measurement mode operation for outputting the first control signal having a first frequency to the first chopper amplifier circuit;
- and a test mode operation for outputting the first control signal having a different frequency from the first frequency to the first chopper amplifier circuit.
A control method of controlling a biosignal measurement device,
- wherein the biosignal measurement device includes a first chopper amplifier circuit that receives a biosignal detected by a first electrode contacting a living body, and is chopper-controlled based on a first control signal, and
- the control method comprises selectively performing one of:
- a biosignal measurement mode operation for outputting the first control signal having a first frequency to the first chopper amplifier circuit;
- and a test mode operation for outputting the first control signal having a different frequency from the first frequency to the first chopper amplifier circuit.
